Checktestdata

Checktestdata is a tool to verify the syntactical integrity of test cases in programming contests like the ACM ICPC.

It allows you to specify a simple grammar for your testdata input files, according to which the testdata is checked. Two sample scripts hello.ctd and fltcmp.ctd are provided for DOMjudge sample problems hello and fltcmp.

Installation

Requirements:

recent g++ (>= 4.7)
Libboost and the boost::regex extension
The GNU GMP libraries (http://gmplib.org/)
flexc++/bisonc++ (optional)

If you don't have flexc++ and/or bisonc++ available, you may use the release branch where we've pre-generated the scanner/parser files.

Command line for installing the build dependencies on Debian or Ubuntu, when using the release branch:

apt-get install make g++ libboost-regex-dev libgmp3-dev

For Redhat-like distributions try:

yum install make g++ boost-devel gmp-devel

To compile checktestdata, run:

./bootstrap
make dist
make

Leave out the make dist step if you use the pre-generated scanner/parser files on the release branch.

Library

The commandline program is built upon the separate library libchecktestdata.hpp (see checktestdata.cc as an example for how to use this library) that can be used to write the syntax checking part of special compare scripts. It can easily handle the tedious task of verifying that a team's submission output is syntactically valid, leaving just the task of semantic validation to another program.

When you want to support presentation error as a verdict, also in variable output problems, the option whitespace-ok can be useful. This allows any non-empty sequence of whitespace (no newlines though) where the SPACE command is used, as well as leading and trailing whitespace on lines (when using the NEWLINE command). Please note that with this option enabled, whitespace matching is greedy, so the script code

INT(1,2) SPACE SPACE INT(1,2)

does not match 1__2 (where the two underscores represent spaces), because the first SPACE command already matches both, so the second cannot match anything.
